Earl Domnall of Laigin

Earl Domnall Ua Cheinnselaig of Laigin (1047-), also known as Earl Donal Kinsella of Laigin, was the Earl of Laigin (Leinster) under King Einri of Eire during the late 11th century. Donal Kinsella agreed to become a vassal of King Einri in 1090 due to Einri's status as an Irish Catholic hero for his role in the First Crusade, and he continued to rule over Leinster.
